MICHAEL BRENNAN, MD appears in the CMS NPPES registry as a Pediatric Endocrinology Physician provider holding MD credentials at 301 E WENDOVER AVE, GREENSBORO, NC, 27401, with a listed phone of (336) 272-6161. NPI 1679521140 was issued on 05/05/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what BRENNAN most recently submitted to CMS rather than a vetted directory listing, which is why patients should always confirm the practice is still at this location before scheduling.

Medicare Part D records for calendar year 2023 show 388 prescription claims written by this provider, covering 30 Medicare beneficiaries and totaling roughly $166K in drug spend, split 55% brand-name and 45% generic by claim count. These figures capture only Medicare Part D — commercial insurance, Medicaid, and cash-pay prescriptions are not included, and any drug-beneficiary cell under 11 is suppressed by CMS for patient privacy. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 83.6709/100 for the 2023 performance year (Quality 84.5658, Cost 67.7046), compared with the national average of 83.1.

Pediatric Endocrinology Physician is a narrow specialty nationwide, with 1,457 enrolled providers across 51 states and an average of 151 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline. Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating. Inclusion here does not imply a recommendation, and absence of complaints or sanctions on this page does not mean none exist — always verify credentials through the NPPES NPI Registry, your state medical board, and the ABMS or AOA before making healthcare decisions.
